FLUSHING-CART.

Specification of letters Iatent.

Patented Jan. 9, 1917.

Application filed March 24, 1916. Serial No. 86,381.

To all whom it may concern:

Be it known that I, JACOB I. BRORBY, a citizen of the United States, residing at Shenandoah, in the county of Page and State of Iowa, have invented certain new and useful Improvements in Flushing-Carts, of which the following is a specification.

This invention relates to street flushing carts and more particularly to that class of such apparatus primarily adapted for use in flushing paved streets. f I

The primary object of this invention is to construct a flushing cart of the class set forth which shall embody important features designed to add to the utility and effectiveness of operation of the apparatus.

A further object of this invention is to provide a flushing cart with flushing nozzles so arranged as to present the Water stream to the surface of the pavement in such a way as to secure the best results. i A still further object is to provide a flush-v lng cart of. the character described with means whereby the flushing heads may be located in close proximity with the ground, means being provided whereby the heads may be moved toward or away from the pavement to compensate for irregularities therein to prevent breaking of the heads from striking irregularities. I

With the foregoing and other objects in view, as will from time to time appear, this invention consists in the peculiar combination and arrangement of the various cooperating elements of a flushing cart as hereinafter described and more particularly set forth in the appended claims. r

Referring to the accompanying drawings forming a portion of this specification and illustrating the preferred embodiment of the invention and in which the. same reference characters indicate the same parts wherever usedFigure 1 is a side elevation partly broken away showing the invention; Fig. 2 is an enlarged view of one of the flushing heads with parts broken away; Fig. 3 is a rear view of the cart.

5 designates the usual tank supported by axles 6 carrying wheels 7. A pipe 8 communicates with the tank 5 and carries a cross end member 9 from which depend piping extensions 10 provided with flexible tubing 11 connected with the flushingheads 12suspended loosely from the center of thefaxle 6 by means of chains or other suitable flexible members 14. a

Each of the flushing heads comprises an upper cylindrical member 15 having an open extension 16 adapted to receive the flexible pipe 11, a threaded extension 17 and a socket member 18. The lower end of the cylinder 15 is threaded at 19 to receive a second cylinder 20 having an internal shoulder'21 upon which rests a collar 22 supporting a pipe 23 threaded at its lower end 23 to support an L 23 into which is threadeda fiat flushing nozzle 24 adapted to deliver liquid along the roadway in a path substantially parallel to the ground. By placing the nozzle 24 so that it delivers the water in this position a most effective cleaning of the roadway is accomplished and the stream of water is 'pre vented from looseningthe sand or soft filling between the bricks or stones of a pavement of this type. i i

The member 23 extends upwardly within the upper cylindrical member 15 and is there provided with a rod 25 which it engages by means 'of 'aT head 26, the rod 25 extending upwardly through a stuffing box formed in the threaded member 17 which is closed by'means of a member 27. At its upper end the rodjis provided with a universal coupling 28, from which extends a rod 29 adapted to terminate within easy reach of the drivers seat and'to be provided with means (not shown) for turning the same.

A' U-shaped' member 30 is mounted to swing vertically in hangers 31 upon the base of the tank 5 andthe ends thereof inserted in the sockets 18 ofthe heads 12. At a point intermediate the hanger 31 and the socket 18 theirod carries, by means of a bolt 32, a depending shoe member 33, having a fiattened tread portion 34 extending directly below the nozzle 24 and adapted to lie between it and the roadway.

The operation of the device is as follows: Water from the tank 5 is fed by the pipe 8 to the extension 9 and corresponding extensions 10 and through the flexible piping 11 to the extension 16 of thehead 12, and thus to the interior of the member 15 and downwardly out through the pipe 23 to the nozzle 24 where it is spread in a flat longitudinal stream substantially parallel to theroadway. In order that the best results may be o ta n d the eQ -Zl 2% we b a 9 9 .r he

7 ground or roadway as possible. In order to avoid injury to the nozzle by means of any inequalities in the roadwaywhich would strike the nozzle if left in its proper position to secure the desired result, the shoe 33', with its flattened member as, is placed underneath the nozzle 24, so that if at any time there,

be any obstruction whichwould strike the nozzle 24 the shoe would ride up over sald obstruction, carrying the nozzle and.

the head 12 with it, the head 12 being free to move, due to the loose suspension by the chains 14 and the flexible piping 11, the member 30 being adapted to swing up and down in the hangers 31 in order to accommodate such vertical movement.

If it is desired at any time to change the direction of the spray the pipe 23 and the corresponding nozzle 24: may be rotated upon the shoulder 21 by means of the rods 29 and 25 as will be obvious.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention ceuld be made, without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in "a limiting sense.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: I

1. In a flushing apparatus, the combinav tion with a cart having axles, flushing heads,

means carried by said axles adapted to support said flushing heads to permit a vertical movement thereof, and means carried by said heads adapted to automatically cause said vertical movement to compensate for irregularities in the roadway traversed by said cart. 7

2. In a flushing apparatus, a cart, flushing heads, nozzles carried by said heads, means for changing the angle of direction j of the stream from said nozzles, means for automatically causing a vert cal movement of said heads relative to the lrregularities 7 in the roadway carried by said cart, and

means for preventing of said flushing heads.

8. In a flushing apparatus, the combinahorizontal movement 'tion with a cart having axles, flushing heads,

flexiblemeans carried by said axles adapted to support said fiushingheads to permit Ver- .shoe to cause the head to move vertically in order to clear such obstruction.

i. In a flushing apparatus, the combination wlth a cart having wheels and axles, of

'a tank supported thereon, fiushing heads,

means for supplyingfluid from said tank and said heads, flexible means carried by said axles adapted to support said heads to permit vertical movement thereof, nozzles carried bysaid heads, means for-changing the angle of delivery of said nozzles, a shoe underlying each of said nozzles, means carrying said shoes adapted to prevent horizontal movement of said heads whereby the heads may be lifted by said shoe upon said shoes coming in contact with inequalities in the road. 7 i V V 5. A flushing apparatus comprising a cart,

a U-shaped member supported by said cart and carrying flushing heads at either end thereof, meansfor supporting said flushing heads from the axles of said cart in such a manner as to permit vertical movement of said heads, flexible connections for supplying fluid to said heads, a shoe adapted to underlie each of said heads and contact with the roadway whereby inequalities in the roadway are adapted to be engaged by said shoes to lift said heads over said inequalities in order to prevent injury to said head.

In testimony whereof I affix my signature in presence'of two witnesses.
